-Referring indetail to the drawings; and-for the present tojFigs; 1 to2; a form section [0" comprises an" arch or crown member II" and aninvert member or portion I2. The arch member is -hin'ged' at l-3 andl4,so it can be collapsed forFpassa-ge through a similar section,"as' willbe describedi'n detail later. The portions'of the 5 form section arecomposed of spaced circflinferenti'al'ribs I5 connected by longitudinalreinforcing angles l6 and sheath'ing' plates" |1.

The overhanging ends of the beams 26- are provided with hangers 4| onwhich rolls 42 are journaled. Trolley beams 43 are movable on the rolls42. Hold-down. rolls 44 are journaled in the flanges of the hangers 4|.The beams 43 are provided with trolley hoists 45. A single centraltrolley beam may be used if desired, instead of the two side beams, asshown in Fig. 2a.

Contractible ratchet members 46 are secured to the ends of the beams 21and to channels 41 on the side portions of the arch member.

The manner of using the structure described above will now be explainedwith reference to Figs. 3 through 10.

As indicated in Fig. 3, it is usual to employ two arch members 48 and49, and three invert members 50, and 52. Fig. 3 shows the position ofthe traveler and the trolley beams when the concrete has been pouredaround the arch member 49 and the invert member 52 disposed adjacent theheading 53. This concrete for the invert or bottom portion of the liningmay be poured from cars 54 (see Figs. 2 and which travel along a trackconnected with the rails 31, and up an incline 55 to the deck 28. Theconcrete for the upper portion is usually placed through pipes bypneumatic pressure or by pumping. During the pouring operation, thetraveler is secured to the arch member of the form by bolts 56connecting the flanges of the beams 24 to angles 51 welded to the ribsl5. When the pouring of concrete has been completed, the incline 55 istaken down, the bolts 56 removed, and the traveler moved away from theheading by the length of one form section (conveniently about 18 feet)to about the position indicated in Fig. 4. When the traveler has beenwithdrawn, the heading is advanced by mucking in the usual manner. Tofacilitate this operation, each invert member is provided with a switch(not shown) whereby cars 58 may 31 in the foremost lining section. Inthis way, an empty car coming through the tunnel may be placed on oneside of the foremost invert section, by properly manipulating theswitch, so that a full car on hauled out while the first car is beingfilled. The switches on the invert sections are such as to permit themto pass a car along the center rails of the invert sections behind thatadjacent the heading.

After the heading has been sufficiently advanced, it is necessary tomove an invert and arch member forward to constitute anadditional liningsection. Fig. 5 illustrates this operation. The first step is to movethe trolley beams rearwardly, secure the invert member 58 to the hoists45 therefor, and lift it. The jacks 39 are then positioned and extendedsufficiently to support the traveler on the arch member 48. The feet 29are then raised, as indicated in Fig. 6 and at the left-hand side ofFig. 2, whereupon it is possible to advance the hoists 45 and move theinvert member 5!! forward under the traveler to a position as indicatedin Fig. 7. The feet 29 are raised by manipulating the ratchets 33.; Inaddition to supporting the traveler on the jacks 39, 51 by the bolts 56.

The next operationis the collapsing of the arch member 48. to lower thefeet 29 so The first step in this operation is that the wheels 34 again75 rest on the rails 35, as shown in Fig. 7. The jacks be diverted toeither pair of rails 35,

the other pair of rails can be The angles 51 remain secured to the beams24 or, if not previously attached, are bolted thereto. The ratchetmembers 46 are then operated to pull the side portions of the archmember inwardly about their hinges l3 and 14. It will be understood thatthe concrete surrounding the arch member 48 and the invert member 5| hasmatured sufficiently to permit removal of the former. The ratchets 33are then operated to permit the feet 29 to be retracted into the legs23. Since the traveler is not supported independently of the wheels, itis lowered so that the top of the arch member 48 clears the innerflanges of the ribs in the arch member 49. This lowering of the carriagealso lowers the trolley beams, but the hoists 45 can be taken up tomaintain clearance between the invert forms 59 and 52.

The next step is to advance the traveler to the position shown in Fig.8. When in that position, the invert form 59 is lowered into place, therear edge being secured to invert form 52, and the forward edge beingsupported on a'bulkhead 59. Intermediate supports can be placed underthe invert member 58, if desired, to sustain the weight of the travelerwhich is next advanced, as shown 39 are then released.

' in Fig. 9, after withdrawing the trolley beams.

, ticular advantages of the construction described is the fact that itis not necessary'to move the traveler any further ahead than the archmember being-placed. A further advantage is that it is unnecessary tolay rail on the previously completely section to permit advancement ofthe form. It is necessary, of course, to lay rail to replace that on'the invert memberwhich is moved forward, but it is not necessary thatthis be completed before such forward movement can be effected. There isthus no delay, as the additional rail on'the floor of the completedportion of the lining can be laid while the forms are being placed atthe edge of the section last poured. A further advantage is that theinvert section is not hinged. This permits it to be made rigid enough tosafely support the traveler and form during forward movement withoutadditional intermediate supports.

Although I have illustrated and described but a preferred embodiment ofthe invention, it will be understood that changes in the constructionand mode of operation may be made without departing from the spirit ofthe invention or the scope of the appended claims.
